Simple laptop battery repair techniques

In addition to concern about using the laptop while its internal maintenance and repair, laptop battery should also pay attention to routine maintenance work, when we use the laptop battery, especially lithium idle for too long or just maintenance, and it is the charge curve and discharge curve are generated a certain offset, the real need for full release of several circular steps to correct the complete restoration of its charge-discharge curve. 

    1. Settings (this is the most related to the cell can repair to the best of the most important step. Please note that we do not need friends) a turn on my computer control panel è è è power options power scheme shown in Figure 1 using the 

 

battery all the time parameter selected items never b the alarm uncheck the two options, aimed at a few percent when the battery down to let the program does not respond when the appropriate action, so that laptop battery The real is done and so that the minimum charge the battery itself to amend its synchronization with the curve 0% 

      2. Charge and discharge: as set finished, finished for release by the principle of full charge and discharge the battery back and forth two or three times to offset the curve of the battery can be repaired over. Note: When must let the battery charge is full, the best approach is to charge off a few hours or overnight, then unplug the power discharge, until the computer shut off automatically. This back and forth at least two cycles 

    Of course, battery use and charging will cause instability in the capacity of the battery down, but the decline was not caused due to aging, so the calibration is appropriate to make this part of the recovery of the lost capacity. Therefore, regular battery calibration is very necessary thing, such as 1-2 months time. 

Such as HP Compaq 383495-001 Laptop Keyboard and IBM Thinkpad R40 Laptop Keyboard laptops or their own power management in BIOS program provides a battery calibration feature, so the use of these two brands of friends can according to the prompts. For those who do not provide this feature the brand's users can follow my steps below: 

1. The screen saver is set to "None" 

2. In the Windows Power Management power scheme will be set to "always open" and shut down equipment related to the following menu all set to "never" 

3. In the Alarms tab will be "low battery alarm" is set to 10%, the operation is set to "do nothing"; will be "a serious power shortage alert," set to 3%, operating as a "standby" 

4. The screen brightness to the highest 

5. Sure all windows closed, and save the data of all previous work 

6. Check that the battery charge after more than 80%, unplug the power and all external devices, then if the screen automatically reduces brightness, then leave it to hit the brightest 

OK, you can go to sleep, the discharge end laptop will shut off the power plug for laptop charging, so attention must be completely filled before turning, then plug the power back to the program prior to calibration settings. 

(A) causes damage to the battery 

   Gateway MX6423 Laptop Keyboard Notebook computer battery a long time, often charge less for electricity, and even shows the battery is damaged, the specific performance of a larger resistance, the voltage across the charging up faster. So easy to charge control circuit is determined to have been filled, the capacity will naturally decline. Since the battery internal resistance is relatively large, the discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that the voltage is not enough, lack of electricity. Comparison of the discovery of short battery life, should take appropriate measures. 

(B) of the battery refresh program restore the battery discharge time 

Great brands have a laptop battery refresh program, we can use it to repair the battery. For example: a IBM Thinkpad 390X Laptop Keyboard
/262650-based laptop, the distribution for the nickel-metal hydride battery (Ni-Mh) battery, the usual charge and discharge properly, causing the battery discharge time is shorter and shorter, leaving less than 5 minutes, if carrying a laptop to go to work, then it is very inconvenient, what can restore the battery discharge time? 

For the above, we can use the IBM has launched a battery refresh program to refresh the batteries, discharge time to recover, the specific method is as follows. 

(1) the use of AC power to the notebook computer, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe provided to download the IBM notebook computer batteries TP390/390e/390x refresh program. 

(2) Restart computer, press F8 key to enter boot menu and select Safe Mode DOS. 

(3) into the directory where the file you just downloaded, perform a battery refresh program isbr0lww, exe, reading the warning message, as required to insert the floppy disk, and then press the Enter key to execute the self-extracting operation. 

(4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Message. 

(5) follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, the discharge is completed, the system will automatically shut down. 

(6) The battery temperature is high at this time should not start right away, let the battery cool for a while, plug the AC power. 

(7) Boot the computer with a floppy disk, the Autoexec. bat file will automatically run the flash program, and asks the user whether to proceed. Select yes, press the Enter key. 

(8) At this point, flash program to start to refresh the battery, the process soon, when the return to DOS prompt A:> when that refresh is complete. 

(9) Turn off the computer, and recharge the battery until the light turns green so far. 

(10) The above process is repeated three times to get the best results. 

In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be exactly the same nature, with some slightly lower quality long after the beginning of aging, and damaged the whole (series after) the discharge curve. Interest and ability of readers to try to open the battery pack, with the help of the multimeter, you can quickly find the damage to the batteries (voltage error). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.
